TRACK FOR MINE CAB-S.

Application filed EZarch 20, 1990.

and useful Improvements in Track Brakes for Mine Cars of which the following is a specification.

This invention relates to brake means for mine cars and the principal object of the invention is to provide chock means for the cars with means for automatically moving said chock means into inoperative position by the cars.

Another object of the invention is to provide the chock means with springs so as to absorb the shocks caused by the car wheels striking said checks.

Stillanother ob ect of the invention is to place the chock means in openings formed in the rails and their supports so that the chocks will pass below the treads of the rails when in inoperative position.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail. reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which 1- Figure 1 is a side elevation of a cage in the shaft and a part of the track approaching the shaft.

Figure 2 is a plan view of Figure 1.

Figure 3 is an enlarged view of a pair of the chocks or horns and their supporting means. I

Figure 4 is a. detail view.

Figure 5 is a view of a modification.

In these views A indicates the shaft of a mine in which the cage 1 operates and B indicates a gallery of the mine leading to the shaft and on the floor of which is arranged the track 2. 3 indicates a track located on the floor of the cage and arranged so that the cars can be passed from track 2 thereon when the cage is stopped at the gallery.

As shown in Figures 3 and 4, in carrying out my invention I arrange a pair of shafts at on the bottom of the cage, said shafts being Serial No. 357,564.

rotatably supported by the bearings 5 secured to the bottom of the cage. Each shaft is provided with a pair of arms 6 and a central arm 7. The arms 6 support the checks or horns 8, each of said chocks or horns having'a tubular part 9 which slidingly engages the arms 6 and a spring 10 is placed on said arm and tends to hold the horn in its outer position. The horn is provided with a beveled edge 11 and the horns are so arranged that these beveled edges are located adjacentthe front and rear of the cage so that a car being pushed on the cage from either direction will strike said beveled edges of the horns and force said horn down wardly through the openings 12 formed in the rails and the floor of the cage, in this action the shafts at will rock in the bearings. The arm 7 Figure 2 is connected by a link 13 with a lever 14- which is pivoted intermediate its ends to the bottom of the cage. A. spring 15 connects said lever with a part of the bottom of the cage and tends to hold the parts in a position with the horns projecting above the rails. This lever is connected by the cable 16 with a bell crank.

lever 17 mounted on thewall of the cage Figure 1 and said bell crank lever'is connected with a plunger rod 18 which is slidably supported on the wall of the cage by bracket 18 as shown. The cable 16 passes over suitable guide pulleys 19 and this cable passes down alongside one wall of the cage, through an opening in the floor of the cage and across the bottom of the cage to said lever. The parts are so arranged that when the bell crank lever is moved by the rod 18 the cable will be pulled upwardly to move the lever 14 against action of the spring and rock the-shaft 4 to swing the horns downwardly below the rails.

A shaft 20 is rotatably supported under the track 2 in the gallery and this shaft is provided with an arm 21 which extends upwardly between the rails of the track so as to be struck by a car traveling along said track. This shaft 20 is geared to a vertical shaft 22 which is journaled in a suitable support located in the gallery. The upper end of this shaft 22 carries a toothed wheel 23 which engages a slidable rack bar 24: supported in guides 25. This rack will be in alignment with the bar 18 when the cage is stopped with its track in alignment with the track 2 of the gallery.

Supposing that the cage has been stopped at the gallery and one or more empty cars are on the cage, the checks holding the cars against movement. When a full car is pushed along the track it will strike the arm 21, which is held in a raised position by the weighted arm 21 connected with the shaft 20, so that said shaft is rotated and this movement of the shaft will cause the vertical shaft and its toothed wheel to move the rack bar 24 forwardly and this bar striking the rod 18 will pull the cable 16 so as to rock the shafts 4 to lower the horns. The full car will then strike the empty cars on the cage and will push "them off at the other side of too cage and as the full car moves along the track of the cage it will strike the horns at the far side and thus be prevented from moving of" the cage. As the full car strikes the straight side of the horns said horns will slide on the arms 6 against action of the springs 10, and said springs will act shock absorbers and prevent damage to the cars.

If desired the lever 14: may be connected with the horns at the far side of the cage and not with the horns the near side as these horns at the near side will be depressed by the weight of the oncoming car striking the beveled edges.

If the cage is to receive cars from the opposite side then a duplicate set of supporting meansfor the other shaft at will be nec essary.

In the modification the bell crank and cable are replaced by the rack 25 and the shafts 26 and gears 26. In. this type of operating device all four of the horns will.

be actuated at the same time.

It is to be seen that the device is entirely automatic in its action and as the horns disappear below the rails there is nothing on the floor of the cage for the cars to bend or break if they should become derailed and there is no difiiculty in putting the cars back on the rails. All parts are located below the floor of the cage with the exception of the bell crank and its operating rod and the cable and the bell crank and operating lever are placed high enough to, be out of the way of the car so that there is nothing but the cable to be struck by the derailed car. The disappearing horns will also prevent the coal from loding behind them and preventing themfrom operating.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. Car braking means for mine cages comprising a pair of shafts journaled in the bottom of the cage, a pair of arms on each shaft, horns having tubular parts receiving said arms and parts projecting through the floor of the cage, each of said parts having a straight edge and a beveled edge, springs on the arms for holding the horns in their outer position and means for rocking the shafts to retract the horns below the floor of the cage.

2. Braking means for mine cages comprising a shaft journaled on the under side of the floor of the cage, arms on said shaft, horns slidably mounted on said arms, a spring on each arm for holding the horn in its outer position, each of said horns havii'ig a part projecting through the floor, a lever pivoted to the bottom of the floor, a link con necting the same with the shaft, means engaging the lever for holding the shaft in position with the horns projecting through the floor, a plunger rod slidably mounted on one wall of the cage, means actuated by said rod for moving the lever to rock the shaft to move the horns into inoperative position and means actuated by the approaching car for reciprocating said rod.

3. Braking means for mine cages com prising a shaft journaled on the under side of the floor ofthe cage, arms on said shaft horns slidably mounted on said arms, a spring on each arm for holding the horn in its outer position, each of said horns having a part projecting through the floor, a lever pivoted to the bottom of the floor, a link connecting the same with the shaft, means for engaging the lever. for holding the shaft in posit-ion with the horns projecting through the floor, a plunger rodslidably mounted on one wall of the cage, means actuated by said rod for moving the lever to rock the shaft to move the horns into inoperative position, means actuated by the approaching car. for reciprocating said rod, said means consisting of a shaft, an arm carried thereby and adapted to be struckby the approaching car, a vertical shaft geared to said first mentioned shaft, a toothed. wheel on said vertical shaft and a rack bar engaged by said toothed wheel and adapted to strike the said rod.

In testimony whereof I my signature.

JAMES F.. YECKEL.
